My son has a Diamondback Recoil Comp MB with Shimano M355 brakes. The rear brake lever got messed up somehow. The snapring that holds the plunger/piston into the master cylinder assembly got popped out and is missing.
I was hoping someone knows the part number for this snap ring so I could buy that rather than a whole new brake lever assembly.
Does anyone have a parts manual or parts sheet/drawing of this brake lever assembly?
The part number on the brake lever assembly is Shimano P/N BL-M355.
